Shelton and Stefani were hoping to sing "Nobody But You" at the 2020 ACM Awards, which were supposed to take place in Las Vegas on Sunday night, but due to the coronavirus (COVID-19) pandemic, the show has been postponed. The couple, Shelton shared, are "in Oklahoma, hiding away ... and we're also doing what I think everybody else must be doing, which is drinking all day."

"Not me!" Stefani replied to Shelton, who admitted that he was mostly talking about him. Behind the camera the whole time was Stefani's brother, Todd, Our Country host Gayle King later revealed.

"Nobody But You" is not Shelton and Stefani's first duet together but it's the most recent, found on his Fully Loaded: God's Country collection of hits and new music, released in 2019. The pair released the song to radio in January and shortly after performed it live at the 2020 Grammy Awards.
